Hi All,  

I am trying to make an on axis focault tester for testing F 2 and faster optics, and would like some 
ideas on how to achieve on axis alignment of the slit and knife edge. I was tempted to use a beamsplitter, 
but I am unsure because of the spherical aberation it might induce. Any Ideas?  

Regards, 

Alfredo
